Frequently Asked Questions
What are the benefits of the 5° Valgus Stem Alignment?
The 5° Valgus Stem Alignment features an anatomical stem valgus angle for a natural femoral fit and accommodates offset stems to optimize component positioning.
How does the intercondylar design preserve bone?
It utilizes a bone-preserving intercondylar design with a narrow intercondylar box of ≤22mm, which maximizes bone conservation in the distal femur.
What stability features does the Dual Constraint System offer?
The system provides 0.5° controlled internal/external rotation, 1° varus/valgus constraint tolerance, and features a non-hinged constrained bearing to maintain stability in ligament-deficient clinical scenarios.
How does the Double Locking Mechanism work to reduce micromotion?
It utilizes a NO.1 Locking Screw along with a NO.2 Advanced locking mechanism that reduces backside micromotion to the lowest level.
What are the functions of the Tibial Augment and Tibial Cone?
The Tibial Augment reestablishes joint line alignment, reduces extension gap, and uses a VS wedge design to minimize shear forces. The Tibial Cone features a stepped geometry for compressive bone loading, preserves native joint line position, and eliminates bone graft requirements.
What materials are used for the revision knee system instrumentation?
The RSK™ Femoral Condyle (PS) and Tibial Tray are made of CoCrMo, while the RSK™ Tibial Bearing (PS) is made of Germany UHMWPE.
